Embodiments of the present disclosure relate to a method and an apparatus for alerting threats to users. The apparatus may capture a plurality of signals including at least one of Electro-Magnetic (E-M) signals and sound signals. The E-M signal and sound signals are used to detect objects around the user. A threat to the user is predicted based on the objects around the user and one or more alerts are generated such that the user avoids the threat. The prediction of the threat enables the user to take an action even before the threat has occurred. Also, the alerts are generated based on the prediction such that the user can avoid the threat well in advance of the occurrence of the threat.

Disclosed is a burglar sensor arrangement structure for arranging, with respect to a vehicle interior member (10), a burglar sensor configured to detect an intrusion into a vehicle interior. The burglar sensor arrangement structure comprises an ultrasonic wave generation unit (2) for generating an ultrasonic wave, and a throat portion (18) for radiating the ultrasonic wave generated in the ultrasonic wave generation unit, from a outside opening (18a) thereof into the vehicle interior, wherein the vehicle interior member is formed with a groove (20), and the outside opening of the throat portion is opened at a bottom surface of the groove.

This disclosure relates to a method of detecting an occupancy state of a living space for controlling an on/off performance of an electrical apparatus. The method comprises using a motion sensor to send wave signal and detect wave signal reflected from a moving human body and using a dual sensitivity detection arrangement including a low sensitivity detection mode and a high sensitivity detection mode respectively performed for identifying the wave signal being a motion signal according to the electrical apparatus being in a turned-off state or in a turned-on state. The dual sensitivity detection arrangement enables the motion sensor to more precisely detect the occupancy state of a living space while minimizing a probability of the electrical apparatus being activated by a noise signal.

This disclosure relates to a method of detecting an occupancy state of a living space for controlling lighting apparatus. The method comprises using a motion sensor to send wave signal and detect echoed signal reflected from a moving human body and using a control circuitry operated with a software program to analyze the echoed signal for establishing a numerical value account. In referring to preset parameters, the software program judges the echoed signal by analyzing time duration and frequency pattern of the echoed signal as an incoming motion, an outgoing motion or a local random motion, such that the numerical value account is accordingly updated to represent actual occupant number for activating the controller circuitry to turn on or turn off the lighting apparatus.

A method includes receiving, by a first wireless device, first data indicative of channel properties of a first communication link between the first wireless device and a second wireless device, the first wireless device and the second wireless device being located in a same vicinity. The method further includes detecting, using a supervised machine learning (ML) model applied to the first data, human movement and presence of stationary objects within the same vicinity and activating, by the first wireless device in response to detection of the human movement, an ultrasonic signal. The method further includes receiving, by the first wireless device, a reflected component of the ultrasonic signal and confirming, by the first wireless device using the reflected component, presence of a human in the same vicinity.
